Question regarding pci_alloc_consitent() and __get_free_pages

Hi,

I have a question regarding the pci_alloc_consistent() function. Will this function
allocate pages that are physical contiguous ? i.e if I call this function with a size
argument of 32KByte will that be 8 consecutive pages in memory on i386 architecture (4
pages on alpha). In general, will __get_free_pages(GFP_ATOMIC, order) always return
physical contiguous memory ?

All feedback appreciated,
